I don't want to speak for others, but the IANA team would want to be
careful and deliberate on this front, and I think those concerns were
shared by others we spoke to when we were analyzing the options. We
also informally polled some of our partners involved in managing and
publishing the root zone to get a read on their readiness to support
this, that influenced our thinking.

So I assume the difficulty here is one of process, not technology -- but if that's the case, RFC 3172 seems fairly clear who the process owner is, and the IAB ought to be able to make an informed call.

I don't think anyone is suggesting the IAB shouldn't be able to make
an informed call. For me, the pragmatic question is, are any problems
with what we asked AS112 operators to do yesterday sufficient to delay
delegation of home.arpa until such time as we navigate the waters
to find a way to use DNAME instead? (Noting that I assume we could
substitute in DNAME later once things are considered ready.)
